CLAMP FOR HOLDING TYPE.

SPECIFICATION forming part of Letters Patent No. 718,622, dated January 20, 1903.

Application filed June 2, 1902. Serial No. 109,976- (No model.)

To all whom it may concern.-

Be it known that I, J OHN A. HANDIBOE, of WVashington, District of Columbia, have invented certain new and useful Improvements in Clamps for Holding Type; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in a clamp for holding a set-up page or form of type, the object being to provide an attachment that can be readily and quicklyapplied to the page or form and be clamped thereto, thus holding the type constituting the page or form in their proper relative positions, thus dispensing altogether with the use of cord now generally employed for this purpose.

With these ends in view my invention consists in a clamp comprising a yoke adapted to surround or embrace three sides of the form or page of type and a cam-bar mounted in the ends of the yoke and adapted to be turned so as to bind the clamp solidly to the page or form of type, thus locking the type in position against a possibility of accidental displacement. 1

In the accompanying drawings, Figure 1 i .a view in elevation showing the clamp applied to a page or form of type. Fig. 2 is a similar view showing the clamped page or form within a chase. Fig. 3 is a view in section, taken through Fig. 2, showing the clamp and the page of type in elevation. Fig. 4 is a view in perspective of the clamp detached, and Fig. 5 is a view in side elevation showing the clamp locked to a page or form of type and also showing a slotted slug at the end of the page.

1 represents a clamp, consisting of the angular yoke 2 and the cam-bar 3. This yoke 2 may be made of round wire or in the form of a flat metal ribbon and carries at its free end the cam-bar 3, the latter being journaled so as to permit it to be readily turned in its bearings at the free end of the yoke. The clamp thus constructed is adapted for a sin gle size page or form. Hence it is necessary to provide various-sized clamps for the different sizes of forms or pages.

After the type have been set into proper form the clamp is placed over the page or solidly and securely held in place against the possibility of accidental displacement.

The cam-bar 3 is preferably made rectangular in shape, with two flat sides 4.4., one fiat I edge 5, and one curved edge 6, and is as long as the yoke is Wide, so as to engage the entire line of type adjacent to the bar. This bar is provided with the pivots 7, which-are located nearer one flat side than the other and are mounted in bearings 8, formed in the ends of the yoke. To apply the clamp, the cam-bar 3 should be turned to bring either its curved edge or its fiat side nearest the pivots against the line of type. After the yoke has been properly adjusted to the page the cam-bar should be turned so as to bring its fiat face farthest removed from the pivots '7 against the line of type, thus firmly clamping the yoke and its cam-bar to the form or page and locking the cam-bar against the possibility of accidental movement.

To enable the cam-bar to be readily turned, I have provided the same with a centrallylocated hole 10, passing transversely through the bar from one flat side to' the other, for the introduction of an instrument of any kind, such as a nail, which will afiord ample leverage for turning the cam-bar.

If desired, I can employ a grooved slug 11 at. the end of the form opposite the end of the cam-bar, the groove being formed at the outer face of the slug. In setting this form up in a chase I employ the ordinary furniture 12, such as is now commonly used, the pieces adjacent to the form being grooved to receive the yoke. Where a grooved slug is used, it may not be necessary to use furniture at that end; but in the event it should be it will not They also dispense altogether with the use of cord, now universally employed for locking the forms or pages, and permit the page or form to be removed from its chase and the furniture employed therewith used on other work, thus greatly reducing the number of pieces of furniture required on work of this character.

It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particularconstruction and arrangement of parts shown and described; but,

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A clamp for a page or form of type, comprising three members fixed relatively to each other, and a cam-bar carried by said clamp and constituting the fourth member of the clamp.

2. A clamp for a page or form of type constructed and adapted to be removed from said page or form, and comprising three members fixed relatively to each other, and a cam-bar constituting the fourth member of the clamp, said cam-bar mounted at its ends in the free ends of two of said first-mentioned members.

3. A clamp for a page or form of type, comprising a yoke having three integral members, two of which are parallel with each other, and a cam-bar pivotally connected at its ends to the parallel members of the yoke and connecting said members.

4. A clamp for a form or page of type, comprising a yoke adapted to embrace three sides of said form or page and a cam-bar mounted in said yoke, the said cam-bar having two fiat sides and an intermediate curved edge, one flat side being farther removed from the axis of the cam-bar than the other.

5. The combination with a clamp comprising a yoke adapted to embrace three sides of a page or form of type and a locking cam-bar mounted in the open end of said yoke, of a chase and furniture for locking the form or page in the chase, the sections of the furniture adjacent to the yoke being grooved, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
